To all whom it may concern:

Be it known that I, RonnnrHorn-Jonns, of North Tonawanda, in the county of N1- agara and State of New York, have invente certa n neyy anduseful;Improvements in fi'cation, and to the reference-numerals marked thereon.

My present invention relates to musical instruments and more particularly to organs or instruments havingv the same general scheme of construction, and it'has for its object to provide a simple and efi'icient.

means for releasing the stop keys from the influence of other operating means in order that they may be operated manually, when desired, independently of such.

. A further object of the invention is to accomplish this result in an improved man- ,ner through the medium of a simple arrana'ement of electrical devices.

To these and other ends the invention consists in certain improvements and combinations of parts, all as will behereinai'ter more .fully described, the novel features being showing the positions of the parts after the stop is drawn: Fig. 3 is a fragmentary view of the same parts showing the initial pos1- ticn assumed by the finger portion of the stopkey when operated. Fig. 4 is a frogmentary "iew of a modified form; Fig. 5 .is a top plan view of the,l ev shown in Fins: 1 to 3, and Fig. 6 is a detail view of the contacts established through the operation of the key.

Similar reference numerals throughout the several figures indicate the same parts.

I contemplate the use of my invention in connection ,with the stops for the pedal keys of an organ. In organsof one type, arrangements a e made wherebyin drawing the stops preparatory to performing on one pivotal mo ement.

manual, other stops for the bass or pedal keys are thereby automatically drawn. to

provide. a suitable-bass for that particular manual with regard-to the stops that are drawn upon it. With the ordinary construction of pedal stop keys it has hitherto been I necessary to provide an additional key known as a release tablet for releasing the pedal stop keys from the influence-of the beforementioned automatic operating means which held them in either the in or out position before they could be manually con trolled by their individual manipulation in case it was desired to alter them. This required two distinct movements of the hand of the performer, one to the release tablet and the other to the stop. keys themselves. the practice of the present invention I provide for accomplishing" the release of the stopkeys by manipulation of merelv the keys themselves and bv impartingv thereto a movement-ya continuation of which, operates the key to the desired position.

Referring more particularly toFigl of the drawings, 1 indicates a stop kev pivoted on a rod or member 2 by means of an open bearing 3 on its under side that isheld in engagement with the pivoted member by a spring 4 on a suitable supporting portion 5 of, the organ structure, which spring also 'tends to maintain a key in either of what will later be described as being its in and out positions by passing across the center of inn preferably metallic arm on, or extension Jot. the kcy, 6, mo es in continuous Contact with 'a contact member 'T'mountcd. in the present instance. on a lower rail 8; of the organ structure, but moves into contact with the companion contact member 9 only when the arm is elevated, as in Fig. 1, to the region of tho'oi'l set portion 10 of such contact, as, shown in Fig. 6, the pos tion of the arm being in dotted lines. hen in the raised' 'iosition, therefore, the arm establishes a circuit through the contacts, which circuit, when closed, operates the stop mechanism that the key controls. vIn such case A rcarwardly extendthe forward or operating portion of the key is depressed, as in Fig. 2. and the stop may be said to be out or drawn.

the corresponding suitable bass sto h as used, to warrant its disclosure herein. It

is deemed sufiicient to sayth at the'jmanual stops close a circuit through vires ll and 12 mechanism unit to a pair of oppositely disposed bellows 13 and 14:. One of these bellows, the bellows for instance, has a larger pressure area than its mate so that while both are connected to the arm 6 at 15 and 16, the

former thereby acting to -draw the stop and the larger overcomes the smaller and. negatives its effect, but when the larger is de-'.

fiaiied the smaller acts. to returnthe stop to normal position. The object in providingthe" smaller one is to make possible the automanic-resetting of such stops as are necessary when the performer changes hls F or instance, in drawing wiflies' .to throw out the-suitable? bassfor 'thepreceding manual stops, which bass-is no longer applicable. However, it is only important to the present. disclosure to say that bothbellows are deflated by breaking the circuit through the Wires 11,- 12 as at 2021 hereinafter described which wires are common to both of their circuitsthough these circuits may be separately afi'ectedat otherppints to bringabout the resetting of thejsuit 'ble bass combination as above referred to pyc'he manual stop keys.

n ;A solenoid 11 suitably energized, as by a battery 18 controls the switch 19 that opens and'closes the circuit through the wires 11, 312 at contacts 20 and 21, such solenoid circuit comprising Wires 22 and-23. One of these wires is connected to the arm 6 of the stop key, in the present instance through the mediumjof the contact 7, while theotherleads to anarm 24 on an operating or finger portion 2,5'of the key l'projecting outwardly beyond the rail 5 and 8 to be accessible to the fingers" of "the performer at the key board. -This finger portion 25' moves withthe key-when-the latter is operated in any.

manner but it also has a limited movement relatively thereto and to this end the two parts are connected by a resilient tongue or member 26, shown in dotted lines in the figures, but which is sufliciently stiff to' maintain the parts in the normal relationship shown in Figs. 1 and 2 and to hold the electrical contact arm 24 on the finger portion in spaced-relationship to and between two oppositely disposed contacts 27 and 28- ,both electrically connected to and preferably mounted upon the arm 6 of the key. The range of movement of the finger-piece, hoWeveryrelativel-y to its keypermitsthe Contact arm 24 thereon to-move into enga'ge- 'ment with either of the contacts27 or 28 when the key is manually operated by means of the finger piece to either the in or out position, which engagement, in'the present and the finger portion.

instance, effects a relative disposition of the finger portion and its key adapting. them for further joint movement. ,Such contact' closes the circuit of the solenoid 17, operates theswit'ch 19 and breaks the circuit through 1 the wires'll and 12 thereby throwing out the automaticdevices then in control of the key by causing the deflation of bothof the tionto the-movement of the arm 6 and hence the key is free tomove in eitherdirection bellows 13 and 14, oreithcr'of them. When I both bellows are deflated .there is no opposiwith a continued pressure on the finger por tion. 1

In 'Fig. 4 is illustrated a constructionof the finger piece contact arm 24. that I preferin which embodiment the end of the I arm is looped'or doubled providing'two contacts 27" and 28 on thisarm instead of on the arm 6, which contacts are disposed upon member.
